- .change, allowingthe clerk or operator to deliver. the proper change to a customer makrectly tothe coins. II

A further object is to povide a machine.

I which will be rapid in'its computationand operation and absolutely correct, whereby the frequent mistakes made by clerks and cashiers inmaking change will be avoided.

.The invention conslsts generally in a change-making machine which will add the 'ing shaft having a seriesoi-cam-surfaces and items of purchases and deduct them from the cash deposited or receivedfrom the customer and deliver the difierence in change.

Further, the invention consists in air-dis tributing valves whose operation controls the admission of air to the mechanism for ejectingrthe coins from their cylinders.

urther, the invention consists in rotary changamaking-valves;

Further, the invention consists in means for throwing the carrying mechanism to its operative or inoperative-position. I

- Further, the invention consists in a quarter ortwenty-five-cent piece valve.

Further, the invention consists in providing cylinders having means operated by a fluid-pressure for ejecting the articles therefrom. i I

. Further, the'invention consists in" bill-receptacles and controlling 'valves'therefor. I Further, the invention consists in a revolvmechanismcontrolled by. the revolution of said shaft for operatin the. change-making valves; and, further,t e invention consists in various constructions and combinations, all as herelnafter descrlbed, and particularly pointed out in the claims.

In the accompanying drawings, forming] part of this specification, Fi ure 1 is a see- Fig. 2 is "a side elevation of the machine withthe castional view on the line a wof ig. 2i
